BS41, Matching Tuner for 7MHz Expanded Bandfor 730V Series

This BS41 is a matching tuner designed for the existing 730V-series enable to operate the newly assignedexpanded bandon7MHz. By attaching this unit to the model 730V-1x allows to expand the bandwidth on7MHz. (No modification is required in theantenna.)

Attaching this unit brings to helps the VSWR improvement for the other band other than 7MHz too. TheVSWRcharacteristic for those higher bands (assigned for SSB, FM bands)tend to obtainabetterVSWR.

Ex: 14MHz of 730V-1 enables to cover 14.15～14.35MHz bandwidth at the best VSWR point.28MHz of 730V-2 enables to cover 28.5～29.0MHz bandwidth at the best VSWR point.

Not only those who owns the existing 730V-series for expanding it for 7MHz, but also those who wish toset up V-dipole seeking to operate on the newly assigned expanded frequencies on the 7MHz together, suchas Contest lovers, DX-huntings, rag-chewing with friends, meeting QSO group or party on the air, thisantenna meets the demands and is indispensable.

WIDEBANDWIDTH, YAGI BEAM ANTENNA☆ Enable to Operate 7-Entirely 7.0~7.2MHz CY402 2-Element

CL40DX 4-Element

These models CY402, CL40B-5 and CL40DX are reduced type, Yagi beam antennas assuring a high performance. In thereduced scale type of antenna, a high efficiency will be expected when designing it to set narrow space. Usually the bandwidthis accordingly related to the length of elements, hence these 2 antennas are being applied the entire band by dividing them into3 bands for the model CY402, while dividing it into 2 bands, by which a high performance are ascertained to derive. In thecenter section of the each element is equipped with a band turning switching unit, that enables to change and select the bandwhich is remotely controlled. In the tip of element end for which determines the radiation efficiency and performance, acapacitor rod is attached that gives high loading efficiency, works as electrically equal value of 1.6m longer length thanmechanical length for both models, that almost as good performance as a full-sized antenna presents, along with using alow-loss loading inductor. Mechanically, utmost consideration is taking into account, a swaged and light weight tubing rod ofhigh strength for element, and alumo-welded capacitor rod are using for reducing an unwanted weight and minimize a windsurface area. Each model is required with 13.8VDC power supply for band switching.
